NCT06372184

Brief Summary

Allergic rhinitis (AR) is characterized by sneezing, nasal congestion, nasal itching and nasal leakage and is caused by immunoglobulin E (IgE)-mediated reactions to inhaled allergens. Increasing evidence showed that gut microbiota could influence the development of AR, and we found that washed microbiota transplantation (WMT) could improve nasal symptoms in clinical practice. This clinical trial aims to evaluate the efficacy and safety of WMT for AR.

Outcome Measures

Primary Outcomes (1)

  • Changes in the reflective total nasal symptom score (rTNSS)

    TNSS is expressed as the sum of the scores for the four nasal symptoms (nasal congestion, rhinorrhea, nasal itching, and sneezing) in the past 12 hours. Each symptom was rated on a 4-point scale from 0 (none) through 1 (mild), 2 (moderate), and 3 (severe).

    baseline, one weeks, four weeks, twelve weeks post WMT

Secondary Outcomes (8)

  • Changes in the rhinoconjunctivitis quality of life questionnaire (RQLQ) score

    baseline, one weeks, four weeks, twelve weeks post WMT

  • Changes in the single reflective nasal symptoms score

    baseline, one weeks, four weeks, twelve weeks post WMT

  • Changes in the concentration of specific IgE

    baseline, one day, four weeks, twelve weeks post WMT

  • Changes in the concentration of inflammatory factors

    baseline, one day, four weeks, twelve weeks post WMT

  • Changes in the number of immune cell

    baseline, one day, four weeks, twelve weeks post WMT

  • +3 more secondary outcomes
